Selecting Sen. J.D. Vance (R-OH) as his vice presidential running mate is proof former President Donald Trump isn’t too concerned about winning over undecided and independent voters. The choice says he feels secure about the election, but it also shows the Republican Party’s focus in coming years will stay centered on Trumpism.

While former Vice President Mike Pence represented the staid foil to his boss’s boorish, energetic persona, Vance is a younger, like-minded equal, albeit much more polished and accomplished. And at 39 years old, Vance represents the future of the party in ways Trump simply can’t.
